Cartridge and projectile arrangement

A projectile is created that has a protective ring from in the circumferential direction in the distance ratio to one another present, blunt-pronged or crenellated Elements - in the following for the sake of brevity referred to as senses - has a convex Surrounding nasal tear disk and bridge. The projectile is arranged in a case with the jjase exposed extends beyond the open end of the sleeve. It becomes a chamber with a double diameter and Propellant ignition and gas expansion arrangement according to the so-called "high-low" principle in the cartridge together with a tapered one Tapered and tapered rear end of the bullet applied.

The invention relates to an improved cartridge and projectile assembly, which is of particular value in terms of handling, shooting and "effective target impact" Projectiles which, in an expedient manner, carry a flowable charge of material and in particular carry a liquid asset. Various aspects of the invention also prove to be expedient with regard to improved firing of other projectiles.

There are known projectiles that carry liquid funds for the distribution of the same at the target. In such an arrangement, a "projectile is provided, which is fragile and fired from a cartridge case of _r is the projectile

to its front ends by including the interior of the area open '., iuies the sleeve is protected. if so a satisfactory arrangement for some especially for those who use relatively small cartridges and have sufficient space in the Have the cartridge on the kaiimer so that the projectile can be satisfactorily fired from within the case can be and can move effectively along the barrel bore, but this arrangement surrounding the nose is not below practical in all circumstances and this applies in particular to cartridges of larger dimensions, such as cartridges for large-caliber, manually operated gas pistols - e.g. 37 and 3b now - and 40 mm grenade launcher. In such cases it is advisable to that the section of the projectile running along the bore corresponds closely to the outer diameter of the cartridge case, Uui so to the different diametrical conditions the barrel bore and the cartridge receiving chamber in which the corresponding projectiles are fired, adapted to become. However, if the projectile extends beyond the cartridge case and is fragile in its lawn is designed, it follows that the cartridge during handling ', especially if the cartridge is accidentally dropped onto a hard surface, an inconvenient one Is subject to breakage.

Line of the invention is based on the problem of providing a cartridge and projectile arrangement and a projectile create that makes it possible to adequately protect the projectile if it is appropriately influenced and dropped same.

Another object of the invention is to provide an improved buttock assembly which not only leads to an improved treasure in case of a fall with regard to the tearable nasal segment, but also

if it is advantageous, it also means that the desired break-up properties x> 3i of contact with a target are given, and zv / ar including hard targets at which the projectile fJacii or with an impact, as well as with an impact on the ground or other soft target flat or "at an angle. ■

there is another object on which the invention is based aarin to create a projectile arrangement that leads to a relatively flacxed plague path with a limited flight range, whereby it it becomes possible to use the same under more controlled conditions in connection with circumstances where a greater wing width is not aimed at, as is the case with police work.

There is another object on which the invention is based in creating a cartridge and projectile assembly that had a double diameter chamber and propellant ignition and gas expansion arrangement according to the so-called "low-low" principle in connection with a corresponding “Tit a reduced diameter at the rear end of the projectile is created in order to ensure sufficient combustion of the Propellant and adequate protection of the rear end of the projectile and at the same time it becomes possible to use a to use simple and cheap construction of the parts.

7 shows a broken away longitudinal section of a modified embodiment of the cartridge cases according to the invention. Arrangement.

Referring to the figures, there is a cartridge 11 in FIG Figures 1 and 4 shown, which has a sleeve 21 in which a projectile 31 is attached. The nose 51 of the same extends beyond the open front end of the sleeve 21. the sleeve 21 has a closed base end 23 which carries a propellant charge, as described in detail below, receives for driving the projectile 31 out of the case and through the bore of the gun barrel.

The projectile 31 has a running along the bore Section 41 with a cylindrical outer shape and a nose, which extend in the circumferential direction towards the front Protective ring 71 has, which by a {»teaching number on in the distance-: ratio arranged protective battlements 73 is formed, the towards the front from their basic connections., with / the remaining part of the nose extend. The nose 51 also has a friction disk 61, which is supported by a ringför *, raigen Zerreißsteg 67 is surrounded, which is formed by Reducing the thickness of the nose, for example by using an annular recess 65, see Figure 4. The tear bar is arranged inside the base of the guard ring battlements 73, so that the tear ring 61 can be torn either in front of or behind relative to the battlements 73. That The front end of the projectile nose 51 is defined by the front surface 63 of the rupture disk 61 is formed, and the front surface is formed convex. The same has one that extends forward Dimension corresponding to the forward dimension of the battlements 73, albeit the foremost Surface 63a is slightly forward with respect to the battlements within the yield point of the junction material upon impact can extend, and can continue, if this is appropriate

is moderate, also extending backwards with respect to the battlements. The protective ring 71 formed by the battlements 73 thus serves in addition, a considerable protection of the tear disk 61 due to unintentional dropping of the cartridge II or of the projectile 31 to yield the same, while at the same time it is made possible that the tear disk 61 when the projectile hits at high speeds is torn, as is the case when the bum is fired from the cartridge case 21 in the normal manner.

The protective ring 71 is designed to taper externally inwards in the direction naca at the front, including the convex outer surfaces of the battlements 73, and this also applies to the outer surface of the base part the section 41 of the projectile running along the bore. This proves to be advantageous not only in that that this part can be easily detached from the corresponding form, but also the 'introduction of the Cartridge supports in a chamber and leads to a certain streamlined shape of the nose 61, but at the same time a Desired amount of speed delay of the projectile and limited flight range is achieved. The tapered one Placement of the battlements 73 also tends to aid penetration of some targets, thereby creating a

better penetration of barricades and distribution of the Material F in ι the interior of the projectile upon impact and tearing of the iJasenab-schriittes and other parts of the projectile body results. The battlements 73 are also preferably tapered outwardly at their inner surfaces 73b tapered, and this also aids penetration into the target and leads to better loosening of the Partly from the shape and greater freedom of the forward tearing movement of the tear disk 61 in those Cases where a forward movement of the tear disk can occur at the target impact, as is the case, for example, when the target is impacted with a Angle and the moment of force of the filler material F in

the bullet does not tear in a forward direction the disk 61 to accomplish. The rupture disk 61 can be in various shapes and configurations, and the same applies to the associated tear bar 67, a preferred embodiment of the type shown here a.it a concave-shaped inner surface and a convex-shaped outer surface 63, 63a.

The nose 51 becomes separated to the rear portion of the projectile formed, the one running along the bore along section 41 and tapered rear section 3 having tails 3 5 arranged thereon. The projectile has a filling made of flowable material AF, which preferably represents a partial charge of a very volatile liquid agent, which - when released from German Gescuoß 31 forms tiny particles on impact. An air space is expediently located in the interior of the snout in order to increase the thermal expansion of the liquid F and the Record vapor pressure of the same or of another flowable or distributable material F, if such a material Expansion space is required, as is also the case with some powdery materials that have a high coefficient of thermal expansion own. The entire projectile 31 is preferably made of a fragile, relatively rigid one Made of plastic with sufficient mechanical strength possesses to withstand the starting pressures occurring when the cartridge is fired, as well as sufficient chemical It is inert to the filler material F that a sufficient service life is guaranteed. It is still expedient that the material of the projectile 31 is able to form a sufficient bond such that the liquid or the other part F present therein is hermetically sealed can be. It is preferred that the plastic is weldable, e.g. by turning welding or ultrasonic welding, Line suitable construction for the rotary welding results from complementary stepped shoulders 39

and 55 on the nose and the rear sections of the projectile, If necessary, it can also be used for a special embodiment other connection or sealing arrangements can be provided. Special plastics which prove to be suitable for the construction of the entire storey 31, namely, by using them conventional injection molding processes are glass-filled Nylon types - e.g. 30% glass-filled type 6/6 nylon - and acetal plastics - e.g. as they are commercially known under the Delrin and Celcon trademarks -. It is also possible to use the Projectile or parts of the same made of other materials, such as tempered glass or metal - e.g. zinc, aluminum, lead alloys etc. - to be produced with suitable strength properties in such a way that the forces and pressures that occur are absorbed A calculation can easily be made for a given design and the conditions of the intended application result. -:

As indicated above, the rear portion of the bullet runs behind the annular, along the bore running portion 41 in a tapered manner, see reference numeral 33, and extending from the surface tapered tapering tails 35, which are preferably inclined to stabilize the twist. This also serves to the projectile 31 including the filler material F, a To convey rotational movement, whereby the distribution of the filling material at the impact due to the action of the angular moment of force of the filling material is supported.

The projectile 31 is in the cartridge case 21 by means of a I-linrästr'inglippe and 7 * recess connection held the by an annular, inwardly projecting lip 27 the open end of the cartridge case wall 25 and a complementary one Recess or groove 33a is formed immediately behind the sliding along the bore cylindrical surface 41 adjacent to the VJase end

-fides projectile is formed. Thus, the outer surface of the cartridge wall 25 advantageously the same or approximately the same diameter as the cylindrical Section 41 of the projectile 31 have. ,

The wall 25 can be provided with a suitable thickness such that the necessary cohesive forces result, that withstand the stresses that are placed on the interior of a given cartridge during the firing of the cartridge receiving chamber occur in a weapon, whereby it is Understand that some of the cartridge-receiving chambers of weapons are slightly oversized and thus adequate mechanical strength, ductility and / or elasticity is required for the sleeve to expand, while other chambers accommodating the cartridge are more closely matched and have lower requirements with regard to the cartridge case mechanical strength, ductility and / or elasticity place.

It is advisable that the cartridge case consists of one sufficient teeth and ductile material is manufactured in such a way that a satisfactory release of the bullet from the case at deia The cartridge is fired. In the case of the specifically explained here Embodiment belong to the deformable by means of injection molding Materials for the sleeve 21 include thermoplastic Plastics such as those based on polycarbonate, polyethylene, polyurea, polypropylene and polystyrene with impact resistance. Furthermore, the sleeve can also be made of other materials, such as metal, including brass, Aluminum, steel etc. as well as tougher and impact-resistant rubber compounds and other elastomers with sufficient mechanical properties Strength and ductility.

external configurations exist as this for a given Area of application proves to be appropriate. Inside the Base 23 of the cartridge case 21 is an ignition charge 91 to be ignited by impact, which ignites a suitable ignition charge Driving agent mixture 93 allows the inside of a Bore 92 is present with a reduced diameter, wherein a the loading plug 81 closing the bore extends over the entrance the bore 92 with reduced! Diameter extends and This effectively creates a chamber with limited Volume for taking up the propellant charge 93 and for the subsequent limitation and time delay Release of propellant or propellant gases during firing, as described below, is formed. if Various propellant compositions can also be used, a suitable propellant composition provides the one that is in the V.St.A. commercially fermented under is called WC Blank. An amount of about 1 g of the same is sufficient for a sufficient launch and Launch a projectile to give a weight of approximately 67 g and an outside diameter of approximately 37 Mn on section 41.

The loading plug 81 according to the preferred embodiment, according to FIG. 4, is in the form of a cylinder having an outer annular wall 85 which is arranged in a frictional fit inside the bore 92 and has a locking lip 35a which is thereon in an opposite relationship with respect to the Rubbing agent charge 93 is formed.

Air can escape and there can be a beveled portion 92a be provided at the front edge of the bore 92 »to in in the same way to facilitate the introduction of the loading plug 81 into the bore 92. It is practical that the grain size of the propellant mixture 93 is sufficient such that a leakage of a quantity of the same through the axial Drilling c53a is prevented, or that the drilling otherwise is effectively closed by contact with the protruding rear end 37 of the snout 31. Indeui the hole 83a is made very small, or otherwise one refrains from achieving a pressure equalization of the air, by eliminating the bore 83a; you can see the rear end 31 with your small cross-section of the projectile in a slight distance from the middle pin or Zinne 83, or else this occurs in the course of the production in mass production, i.e. there is then a correspondingly small gap. The loading plug Bl can be made of various materials that are listed below Pressure can be deformed and this can be thermoplastic. Plastics such as Uylon, Polyäthylen ^ etc. are used. The material is also preferred for shear stresses tearable, as is the case with the thermoplastic materials mentioned.

When a cartridge is then fired while driving the bolt 31 out of it, the detonator 31 is fired Impact, e.g. by a conventional striker, does not shown, ignited, as a result of which the propellant mixture 23 is ignited, see the schematic illustration according to FIG. 6 and this ignition of the propellant mixture "creates gases which increase the gas pressure inside the chamber, which the Contains burning propellant mixture. This gas pressure exerts a forward motive force on the. Loading plug (jl aas, which does not fold up or in Another way is the collapsible side wall 89 move forward and use the middle pin or pinnacle bl to compress against the end 37 of the small diameter of the projectile 31.

Way moved forward by this gas pressure and deformed and / or sheared off due to its contact with the rear end of the much stronger tails 35 on projectile 31. The loading plug 81 can finally be deformed so that devalued a complete segment-like disintegration into smaller ones Sections due to contact with the tails 35 takes place, even if this does not occur in acblen cases braaaht, especially where there is a smaller effective propellant charge for a given projectile mass per unit area. In any case, see Figure 6, serves to retain the projectile inside the sleeve 21 and the inertial force of the projectile mass together with the opposed contact between the small diameter rear end 37 of the projectile and the loading wad 81 to hold the loading plug in the small diameter bore 92 for a period of time such that a sufficient Burning of the propellant 93 is ensured. This makes the desired use of the propellant which requires a higher than normal pressure for efficient combustion. The loading plug 81 will eventually in the deformed state in the chamber in the form of a cavity moved through the section with enlarged bob, tion of the case wall 25 surrounding the tails 35 and the rear portion 33 of reduced diameter of the bullet 31 is formed. This makes it possible to fully utilize the reduced pressure of the propellant gas acts on the outer 'rear body portion of the projectile. . üu_ at a certain point in time during this burning off of the propellant and the gas expansion, the forward towards the projectile 31 exerted force to be sufficient to the restraining force acting on the projectile, such as they through the snap ring connection 27,33a between the liaise and the projectile 31 and by the inertia of the projectile and the filler material therein

will overcome. A suitable process is when the retention of the projectile in the case by the connection between the same and the inertia forces of the projectile are overcome after the loading plug 81 has been completely pushed out of the bore 92 with a reduced diameter, albeit at this exact point in time is not critical, as a certain amount of forward movement of the projectile can be initiated by the direct forces exerted on the rear end 37 of the same by the pin 83 of the loading plug, while the loading plug has the momentary volume restriction and release function relative to the bore 92 in the Treibmlttelkairaner exercises. In this respect shows that the end 37 of reduced diameter of the bullet allows this deformed extrusion of the Ladepfopfens 81, without that the bullet must move forward to allow this pushing, clan seen that this arrangement of bore double-diameter Ladepfropf and (The reduced diameter of the projectile leads to a special and advantageous propellant firing arrangement of the so-called "hlgh-low" type, which causes sufficient combustion of the propellant while at the same time creating reduced pressures that act on the exposed, outer, rear surface of the projectile, see above that the projectile body can be made with less mechanical strength than would otherwise be required if the full combustion pressure and the combustion effect of the propellant acted directly on the hollow edge portion of the projectile.
